LEARNING TO USE YOUR LCR

Step 7

Press the Fish Alarm on/off button. Notice the indicator in the lower part of the screen indicating the Fish Alarm is on. Now if an object is detected between the surface and the bottom, a short alarm sound will be heard. By pressing the Fish Alarm on/off button again the Fish Alarm is turned off.

Step 8

Steps 1 through 7 have verified that your LCR is working properly. You are now ready to increase boat speed to test the transducer installation. As you increase boat speed the LCR should give a continuous bottom return. With a proper transducer installation your LCR will perform well at speeds over 75mph.

TROUBLE SHOOTING: If at high speeds the bottom return is not continuous or there are gaps in the bottom, then the transducer installation or location is such that air is going under the transducer face. Remember that a transducer cannot work properly through air or through air bubbles in the water. Refer back to the transducer mounting procedure for adjustments or for the other mounting options.

TROUBLE SHOOTING: If when making a hard turn, the bottom reading is lost, it is the result of the transducer coming out of the water during the turn.
